Docker modifies the default storage location

• Start by using Docker info to see the basic information about Docker

sudo docker infocontainers:0Images:5Storage Driver:devicemapper Pool name:docker-253:0-679369-pool Pool Blocksize:65.54 KB backing Filesystem:extfs Data file:metadata file:data Space used:533.9 MB Data Space Total:107.4 GB Data Space Available:106.8 GB Metadata Space used:954.4 KB Metadata Space Total:2.147 GB Metadata Space Available:2.147 GB Udev Sync supported: true Deferred removal Enabled: false Library Version: 1.02. 89-rhel6 (2014-09-01) Execution Driver:native-0.2logging driver:json-filekernel Version: 2.6. 32-431.29. 2.el6.x86_64operating System: <unknown>cpus: 1total Memory: 853.5 mibname:rhel62buildid:lio4:i43u:yfqu:sn45:yoe6:7GTF:< Span class= "Hljs-number" >6agx:vskq:iciv:akwd:3okq:husc

This is a newly refurbished Docker environment, which does not see the path to the current Docker file store. However, Docker uses/var/lib/docker as the default storage location by default.

• Stop the Docker service

sudo /etc/init.d/docker stop

• 1

• Back up the original default/var/lib/docker, then copy to a different location and create a soft link

cd /var/libsudo cp -rf docker docker.baksudo cp -rf docker /<my_new_location>/sudo ln -s /<my_new_location>/docker docker

• Start the Docker service

sudo /etc/init.d/docker start

• Finally, use Docker info to view the update results
